how come my e90 330i's idrive knob had more forcefeedback than the one in my m3?

I noticed that when im scrolling through a last list of mp3s on my idrive screen I have to keep turning it over and over, whereas in my 330i I could hold it slightly turned (not past the point of resistance) and it would keep scrolling on its own (much better interface IMO)

Seems like people didn't cope with force feedback that well, so BMW discontinued it in March 2007.
